We have several off-leash parks around here but I'm too scared to take Reece because he's only 7 lbs. He thinks everyone is nice so he'll run up to any dog wanting to play. He likes to run and wrestle with other dogs, which could have awful results if he starts rough housing with a big dog. Even if the big dog means no harm, he could still squish Reece. Whenever I want Reece to run around, I'll take him to these fenced in tennis courts and set him free. Its not quite as good as a park but at least I know he's safe. I wish our humane society had something like you described. It sounds great.
